ELEVATED shaman.

To aZZwkom-it may concem: Be it known-that 1,.CHARIE8-DAYIS, a

citizen of the United States, residing at- North. Plains, in the county of Washi andSt-ateof Oregon, have invented new and which-themate'rial-is contained is automati. cally dumped when the carrler reaches it destination and the carrier thereupon returned to the starting point.

The invention relates more particularly to an improved trip mechanism for such a carrier and its principal object is to provide a simple and inexpensive trip which willbe certain and reliable in its operation and which may be readily applied to carriers of variou constructions.

An embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of an elevated carrier equipped with a trip in which the features of the invention are incorporated;

Fig. 2 is a detail perspective view of the improved trip.

Similar characters of reference designate corresponding parts throughout the several views. I

The invention is not Particularly concerned with the detail construction of the carrier except in so far as it involves an invertible receptacle and a latch element for normally holding the receptacle in an upright position. The carrier is, therefore, shown merely diagrammatically in the accompanying drawings and may be of any suitable construction. The carrier herein shown has a supporting frame 1 provided at its ends with depending hangers 2 which have bearings for the trunnions 3 of the trough-like receptacle 4: in which the material to be transported is contained. The upper bar of the frame 1 is provided with upright standards 5 which carry pulleys 6 operating, as usual, on an overhead track 7.

The receptacle 4- is normally sustained in an upright position by a suitable latch which, as shown, consists'of a lever 8 pivoted on a sleeve 9 adjustably mounted on one of the hangers 2. The inner end of the lever 8 v Specification of Lctter sP atent.

engages: in a notch 10 formed, in". the upper edge of one of the end walls of the carrier oro-fa fixed part 11 secured to the'said. end wall. The lever 8' isrovided beyond. its pivot with an upwardly curved projecting portion 12 terminating in alateral arm. 18;

and said lever is held in anoperative posi tion: by .a,,SPI'1-I1g 14: which extends between the curved projecting portion 12- and the;

The trip mechanism consists of a vertical arm 15 which is: rigidly combined with.v the "lever: 8 and a lever 16 which acts on the upper end of the arm 15 to operate the same and the lever 8. The lever 16 is pivoted between its ends to a bracket 17 secured to one of the standards 5 and projecting outwardly therefrom under and parallel to the rail 7. The lever 16 has its lower end formed as at 16 to engage and operate the arm 15 and its upper end formed as at 16 for engagement with and operation by a trip block 18 secured to the rail 7 at the point at which it is desired to effect the dumping of the receptacle 4. The arm 15 in the embodiment disclosed consists of a pair of bars which are securedagainst one another, z'. 6. face to face, by bolt-and-nut fastenings nd which have their lower ends formed to provide a clamp 19 between whose jaws the arm 13 projects and by means of which the arm 15 is rigidly held upon the said arm 13. In this way, the arm 15 forms, in effect, a rigid upward continuation of the lever 8.

The operation will be readily apparent from the foregoing description. Assuming that the receptacle 4 is latched by the lever 8 in an upright position, when, in the movement of the carrier, the lever 16v engages with its end 1o the block 18, the lower end 16 of said lever will be thrown outward, and will thereupon effect an outward movement of the upper end of the arm 15. Since the lever 8 will move as one with the arm 15, the operation of said arm by the lever 16 will disengage the lever 8 from the notch 10, at which time, the receptacle 4 will be free to over-turn. The lever 16 is free to swing in either direction and on the return of the carrier will ride idly over the block 18. The spring 14 will be of sufficient trength to restore the lever 8 and therewith the arm 15 to their normal positions, the arm 15 at such time bearing with its upper end against the end of the bracket 17 or the end 16 of the lever 16in case the sleeve 9. isset at a p Si-.

tion on the hanger 2 lower than the position shown.- 7

The trip constructed as described constitutes an adjunct which is separable from the carrier and which may be combined with carrlers of varlous constructions and 1s,, therefore, readlly appl1cable to carriers after of a latch element at one end of said frame normally engaging said receptacle to hold the same upright, said latch element being pivoted between its ends for movement in a longitudinal plane and its engaging end be ing upwardly movable to release said re- Gopies of this patent may be obtained for ceptacle, an armupright from said latch element and movable as one therewith in a longitudinal plane, a lever alsormovable in a longitudinal plane, and a bracket to which said lever is pivoted between its ends and which supports said lever from and beyond said frame at an elevation whereby the upper end of said lever will engage said block and the lower end of said lever will simultaneously engage the free upper end of said arm and efi'ect an outwardmovement thereof.

in connection with the operation of said lever by said block. p In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
